What are the best practices for using abstraction in C++?

Abstraction in C++ helps in hiding complex implementation details. Key practices include using abstract classes, interfaces, and encapsulation.

Can you explain how abstract classes work in C++?

Sure! An abstract class in C++ is a class that cannot be instantiated and usually contains at least one pure virtual function.

What is a pure virtual function?

A pure virtual function is a function declared in a base class that has no implementation. It forces derived classes to provide an implementation.

How does encapsulation relate to abstraction?

Encapsulation is about bundling data and methods that operate on that data, while abstraction focuses on hiding complexity. They work together to enhance code modularity.

Can you give an example of abstraction in a real-world scenario?

Certainly! Think of a car: you interact with the steering wheel and pedals (abstraction) without needing to understand the engine mechanics.
